What is a oven tray used for?

An oven tray, also known as a baking sheet or roasting pan, is used for cooking a variety of foods in the oven. It provides a flat surface for baking items like cookies, roasting vegetables, or cooking meats, allowing for even heat distribution. Many oven trays have edges to prevent spills and to contain juices or drippings. They are typically made of materials like aluminum, stainless steel, or non-stick coated surfaces for easy cleanup.
